Namecoin is a decentralized domain name system cryptocurrency that allows users to register and manage .bit domain names without relying on centralized authorities like ICANN. Its key innovation is the integration of DNS functionality directly into a blockchain, enabling censorship-resistant domain registration and ownership while also supporting a coin that can be transferred like Bitcoin. Namecoin pioneered the concept of using blockchain technology for purposes beyond financial transactions, making it one of the earliest altcoins and an important precursor to modern smart contract platforms.
